Marc Deshusses, professor of civil and environmental engineering and global health, is helping to bring sanitary bathroom facilities to people at high risk of diarrheal disease because they lack this basic amenity. He and his team have developed the Anaerobic Digestion Pasteurization Latrine (ADPL) with funding from the Bill & Melinda Gates Foundation. They’re now piloting this low-cost technology at five sites in Kenya, the Philippines and India.
